Android issue about rubichess

[Matthies]

Cool. I was not aware that this code is (almost) ready for Android. I will do some commits in a few moments and you can test again. And I will probably setup this Android NDK later so I can test myself.

Master has some fallback malloc for Android now. Please test again.

Hi! From your last source code. The issue is still there.

[Matthies]

Hmm. Strange.

#ifdef ANDROID
#define allocalign64(x) malloc(x)
#define freealigned64(x) free(x)
#else
#define allocalign64(x) aligned_alloc(64, x)
#define freealigned64(x) free(x)
#endif

Seems that the #ifdef ANDROID doesn't work here. Are you sure this ANDROID is the correct define to check for?

Stockfish uses __ANDROID__ to test for Android compilation. Can you try latest master again and report if it works. I still haven't setup any Android development environment. And I just noticed that Github changes the underscores to some bold font as we can see them in your first report :-)

Nope. Still not working.

I checked the older code, the last "working" one is Ttinqs (#194) bddd8b8

The problem appeared in the next update Eval (#195) bd9d640

It started with "malloc" and later affected to "HashAlignBytes" and "MADV_HUGEPAGE".

I hope that this works now finally. Can you describe in short words how to setup the Android environment? I have installed the NDK but I probably need some more tools or at least set some environment variables to find the correct libs?

Thanks, now it works! Regarding NDK, there is no short description of how it works. :-) You will need to generate android-toolchain for arm7 (32bit) and arm8 (64bit) engines, with appropriate API level for each, separately. After that you'll need to create a batch file, where you have to set paths to android-toolchains and all the necessary flags for android compiles..

[Matthies]

Okay. So I leave the Android stuff for the experts and close here.

@AlexB123 Can you test current master if it compiles for Android? I will release soon and it would be good to check if it is ready for Android.

Hi, sorry for delay with the answer. Yes, engine compiles fine, without any problems. Used source code from here 26fa0c6
